REGISTERING-LOCK.

SPECIFICATION forming part of Letters Patent No. 771,092, datedSeptember 27, 1904.

Application filed December 3, 1903. Serial No. 183,642. (No model.)

To (LZZ 1072 0771, it may concern.-

Be it known that I, J OHN GAELINGTON RA- MEY, a citizen of the UnitedStates, residing at Rome, in the county of Floyd and State of Georgia,have invented a new and Improved Registering-Lock, of which thefollowing is a specification.

The object of my invention is to provide a new and improved lock whichshall register unlocking thereof and at the same time indicate thenumber of times it has been unlocked.

With the above objects in view I have invented the novel lock which willhereinafter be fully described.

The invention consists of the special construction, arrangement, andcombination of parts illustrated in the accompanying drawings, which Iwill describe as follows:

Figure 1 is avertical sectional view through my improved lock, taken online 1 l of Fig. 3

and looking in direction indicated by the arrow, the view showing theparts in normal locked position. Fig. 2is a similar view, but taken online 2 2 of Fig. 3 and looking in the same direction, the view showingthe parts in unlocked position and the indicating mechanism adjusted toregistering position. Fig. 3 is a transverse vertical sectional viewtaken on line 3 3, Fig. 2, and looking in direction of the arrow; andFig. 4c is a detail vlew showing the perforatmg-pin-shoving devlce.

In the practice of my invention I may employ any form of lock-case Aadapted for containing my improved registering and looking devices.While I have illustrated my invention in connection with a lockemploying a shackle B, by simple modification it may be adapted for usewith sliding-bolt and other well-known types of lock.

In describing my invention as applied to A the type of lock illustratedin the drawings,

C denotes what I will term a lower drum or reel, and D an upper drum orreel. On the drums O and D, I arrange a tape E, which may be endless, asshown, or consist of a single length and be wound from one drum upon theother. In the casing a window or sightopening F is provided, and spacedtherefrom in the casing a tape guide or support G is fixedly arranged.The tape guide or support is provided with an opening H, adapted toreceive the forward or perforating end of a yielding pin I, slidinglysupported by spaced brackets J J The pin I is made yielding by a springK, arranged thereon with one end secured to the pin and its other endconfined by the bracket J. (See Figs. 1 and 2.)

L denotes the shackle-locking device, having pivotal support at M. Thelower end of the locking device L is connected with an upper extension Nof a suitably-supported oscillating arm O by a link P. The arm O isadapted for engagement with the rear end of the yielding pin I throughalateral projection Q. (See Figs. 2 and 4.) The lock may be worked by akey R, entered through a suitable opening S in the case A, which whenturned as indicated by the arrow (see Fig. 1) will engage theoscillating arm O.

It will be noticed that the upper drum or reel D is provided with aratchet-wheel T, adapted to be engaged by a yielding dog or pawl V,having suitable pivotal support on the hinged end of the shackle B.

The operation of my improved indicating and registering lock will beunderstood from the above description. The tape E is intended to havenumbers on its face or outer side ranging from 1 up to any desirednumber for which it is adapted. Now obviously when the key is insertedin the keyhole S and turned as indicated by the arrow (see Fig. 1) itwill swing the arm O, and thereby through the lateral projection pushthe pin I against tension of its spring K, and thereby cause the pinsforward or pointed end to perforate the tape and cancel a numberthereon. At the same time and through the extension N and link P thelatch L will be worked, throwing back its locking end, and thereby freethe shackle from locked condition. Continued turning of the key R toposition whereby it may be withdrawn or out of engagement with theoscillating arm O will allow the pin to be retracted from perforatingposition. Now when the shackle B is opened or turned from the positionillustrated in Fig. 1 to the adjusted position shown by Fig. 2 it isapparent that the drum or reel D will be turned through operation of thepawl V and the ratchet-wheel T. Movement of the drum or reel D islimited to the space of one or more teeth on the ratchet- Wheel andpushing action imparted through the pawl V, which is effected uponturning the shackle to raised position.

A look constructed according to my invention has merit over all similarlocks in the construction involved, as well as the simplicity of itsworking parts, which are not so liable to get out of order. It hasutility or usefulness in recording its unlocking and the registering ofthe number of times it has been worked or unlocked.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

The combination in a lock employing a case and pivoted shackle, of apivotal-acting latch, an oscillating arm, means connecting the saidlatch and oscillating arm, the lower end of the oscillating arm beingadapted for engagement and to be shoved, upon turning action of asuitable key, upper and lower drums and a tape which is unwound from onedrum and wound upon the other drum, a yielding pin adapted in operation,for perforating the said tape, means on the oscillating arm adapted inJOHN GARLINGTON RAMEY.
